About Guelder Gardens

Welcome to Guelder Gardens! I am Isabella and I live in Petersfield in the middle of the beautiful South Downs. Guelder Gardens is named after Guelders, the area of the Netherlands where I grew up and where my mother Elisabeth taught me a love of plants and gardens from an early age. As a Dutch native I am naturally fond of growing bulbs and other plants. 


I am an RHS-trained gardener caring for gardens from Petersfield to Salisbury and from West Wittering to London. My gardening expertise includes design and soft landscaping, weeding and pruning, soil, plant and lawn care. As volunteer gardeners in the Physic Garden Petersfield, my husband Fred and I are responsible for the historic vegetable patch. It is very inspiring to research historical plants and vegetables, and to enrich our knowledge while we work.


​I am committed to environmentally-friendly gardening and look forward to creating lively outdoor spaces for you.

Isabella's talent in garden design, upkeep, planning and development is clear in every garden that she works with. Last year, she managed to turn a tangled mess of stagnant water and brambles at the bottom of my garden into what is now a beautiful and flourishing wildlife pond with plants and flowers all around it. Brilliant eye for detail, particularly in subtle compositions of colour and texture, and really impressive knowledge about plants and their particular seasonal needs. I couldn't recommend Isabella highly enough!
